Monographs
This is the first volume in a series of monographs on different aspect< of E.S.R. The book is intended to provide both an introduction to the subject as well 3s serving 3s 3 reference work for practising spectroscopists. The subject matter is divided into a historical introduction, and chapters on the basic theory, experimental techniques, design of cavities. intcrprct3tion of spectr3, and applications. Some m;lthcmatical proofs 3rc contained rn appendices together with the properties of atomic nuclei and field/frequency conversion tables for proton and lithium rcsonanccs. The value of these convcrston tables is doubtful. For the specialist, the chapters on experimental techniques 3nd the design of cavities will no doubt be of value. The final chapter is of wider interest in th3t numerous references arc made to the many and varied applications of E.S.R. The 3uthoritativcncss of the book, as far as the brrsic theory is concerned, IS immediately questioned. however, on rcadtng the first few lines of the introduction. Here it is st3tcd that “energy lcvcls are crc3tcd by intcr3ctions which can This is not an isolated blunder; several take pl3cc between matter and radiation”. other basic misconceptions and inaccuracies are to bc found. I;or example, It appc3rs (p. 16) that the absorption of energy which glvcs rise to E.S.R. spectra occurs “bccausc there IS 3 change tin the magnetic moment of the 3tom. molecule, or radic3l in question”. The book is, thercforc, not to be recommended as an introductton to E.S.R. J.A.L.

This 3ppcars to be the Crst book on 3 topic which h3s 3dvanccd trcmcndously in recent years and is written by a scientist who is 3ctively engaged in research work in this held. The book itself, which is essentially 3 thorough review on the subject, contains I6 chapters each of which ends with a very detailed bibliography. The first chapter gives an tntroductton to the subject and is followed by 3 chapter on the cxpcrimental and technic31 knowhow involved in measuring the IR spectra of adsorbed molcculcs. The following chapters deal wtth 311 the different aspects of the rcsc3rch work that has been carried out in this field. Many of the tables and diagrams in t hcsc chapters arc reproduced directly from the origin31 papers. Chapters 9 and 14 and parts of Chapters IO and I I have been written by two Russian screntrsts. Professor A.V. Kc~slcv and Dr. V. 1. Lygin. 3nd provide 3n cxccllent supplement to l.ittle’s work in this book. The non-specialist will find this a very difficult book to read. However, as a comprchcnsive rcferencc work the &ok wrll be mat useful to IR spectroscopists and surface chemists. E.W.-J. 1. Alo/. S/rucrwr.
